Making a surprise appearance at the London Film Festival – where he presented Charlie and the Chocolate Factory co-star Christopher Lee with an award – on Saturday night, the actor turned heads with his shocking new hair color.

A clean-shaven Depp, whose trademark look usually includes some combination of a fedora, dark glasses, and layers of boho-inspired jewelry and scarves, showed up to the event wearing a simple black tuxedo and black patent Doc Marten boots, offering no explanation for his new ‘do. The 50-year-old is currently at work playing the wolf from Little Red Riding Hood in the fantasy flick Into the Woods, but his brassy, bleached mane looks less canid and more Simba from The Lion King.
